New motorcycle battery, how long to charge? Monitoring a battery's acceptance of a charge can be done in two ways: 1. With a D.C. voltage meter: This involves a expensive meter and a great deal of time. Charge the battery for a set amount of time: anywhere from 1 to 4 hours, let the battery rest for one hour check the electrical state of charge. repeat the cycle until there is no increase in D.C. voltage. This is the Maximum amount of energy the batter will accept. 2. Get a battery hygrometer.

Using a car battery charger How to charge a battery. An average car battery has a capacity of around 48 amp hours which means that, fully charged, it delivers 1 amp for 48 hours, 2 amps for 24 hours, 8 amps for 6 hours and so on. basic charger usually charges at around 2 amps-and so needs 24 hours to deliver the 48 amps needed to fully charge a flat, 48 amp hour battery. But there is a wide range of chargers with different charge rates on the market-from 2 to 10 amps. The higher the charge output, the faster a flat battery is recharged.

When and How to Use a Trickle Charger Plug in your charger and set it to the On position. Most battery chargers have an amp meter that will read higher on a dead battery, and lower to 0 on a fully charged one. If this meter reads low, your battery may not need a charge, or your ground connection may not be adequate.t slowly adds the charge to the battery and does not allow for the normal depletion of charge that batteries commonly have. There are differing opinions of how long a trickle charger can be left on a battery and for that reason, different types have been manufactured.

Speeding battery charging from generators â cheap, effective and relatively simply The cheapest solution for speeding battery charging from generators is to use a basic 20 to 30 amp (230 volt) charger connected to the generator’s 230 volts ac outlet. This will recharge a 100 amp hour battery from deeply discharged to about 80% within about six hours.

- A charger that can charge a standard capacity AAA NiCD battery (180 mAh) in just one hour might take 8 hours to charge a high capacity NiMH (1500 mAh) battery. It's best to ignore such terms and make a rough calculation of how fast a charger can charge batteries.anyo 2500 mAh AA NiMH optimum trickle charge rate is at or below 250mA. One of the reasons it is important for you to understand the optimum trickle charge rate for your charger and batteries is to compensate for the self discharge of NiCD and NiMH batteries.

Determining Charge Time You may actually only see about 1/2 the output over the time period that you are actually charging the battery. For that reason, it can easily take 12 hours or more to fully recharge the battery. Even after 12 hours, because of the reduced voltage, the battery may require more charging to get it 100% charged.

- I have a 12 volt 5 amp/hour sla battery. It says it is rated at a 20 hour discharge rate.. What does that mean. I think that means it is the shortest amount of time the battery could be discharged before damaging the battery.apacity at a 20 hour discharge rate is 5 A*hour. Capacity at a 10 hour discharge rate is 2 A*hour. I just made those numbers up, but the trend is always the same, a quick (short time) discharge gives you less battery capacity (in A*hours).

How long does it take to charge a 12v deep cycle battery with a 10 watt solar panel? Watts = volts x amps a 12volt battery needs an incoming current of at least 13 volts to charge it; 13.5 volts is better. so if the output VOLTAGE of the panel is less than 13 volts it wont do anything.Even if it is, 10 / 13.5 = .74 amp.(three quarters). deep cycle marine battery will typically be more than 40Ah. A 40Ah car battery at 50% charge will more than likely start your car in fair weather. Cold weather is another story. So, to get a completely dead car battery to 50% - 20Ah-would be maybe two days of full sunlight-with only a 50% charge, or about 12.2 Volts.

- A fully charged “12 volt” battery will be at about 12.6V The charger may well take it up to 14.4 or so while charging. About 12.2 volts is 50% and 11.8 is approaching dead. (these voltages at no load, the battery at rest). Anything under 11.0 may indicate a dead cell.uring the constant-current charge, the battery charges to about 70 percent in 5–8 hours; the remaining 30 percent is filled with the slower topping charge that lasts another 7–10 hours. The topping charge is essential for the well-being of the battery and can be compared to a little rest after a good meal.

- Since a 12 volt battery has six cells, any 12 volt lead-acid battery needs at least 13.8 volts to start to charge. This voltage will be enough to fully charge or maintain the battery on a trickle charge, but charging time will be very long at 13.8 volts.To fully charge in reasonable times, alternator output must be 14.2 V to 14.5 V as measured right across the battery posts.Above 14.5 volts charging voltage, batteries have a greatly increased tendency to release excessive acidic vapors, hydrogen gas, and to corrode things around the battery.ince a 12 volt battery has six cells, any 12 volt lead-acid battery needs at least 13.8 volts to start to charge.

How Long Should You Charge AA Batteries? Conventional battery chargers may take up to 8 to 10 hours for charging two batteries. Lithium Ion (Li-ion): One of the smartest of the lot, these batteries monitors the power usage and can save up to 15% of the energy of the battery due to a built-in chip. The typical charge time for these batteries is 3 hours; however, some chargers are known to do the same job in less than 2 hours.

- The lead acid battery uses the constant current constant voltage (CC/CV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.
